This change modifies the query test to use the test template mechanism so that we can capture the plan differences introduced by Postgres 12 pruning append nodes. The PG12 output file also contains a plan change which seems to result in a GroupAggregate being replace by a less efficient Sort plus HashAggregate. This new behavior is still being investigated, but it is still a correct plan (just potentially suboptimal).
